It is 201210136299.4 " a kind of automatic control steam separator " that above-described water separator 12 can adopt application number, can carry out the vapour-liquid two-phase to the solidifying water of vapour ejected in the solidifying water of the vapour from draining into each equilibrium box in evaporating pot, well heater steam drum and boiling pan steam drum and effectively separate.All the other devices all can adopt prior art.
So-called first cream is cane sugar manufacture, and cane milling sugarcane juice out, after clarification, carries out multiple-effect evaporation, is exactly that raw sugar has been starched when 60 hammers are spent.The raw sugar slurry floats processing (or floating) through sulphur and obtains refinery liquor, and Here it is boils sugared main raw material.But can not once boil sugar, all white sugar in syrup is crystallized out, so generally adopt three sections to boil sugar.The first paragraph main raw material is refinery liquor, then mixes retro-dissolved syrup, is diluted to the certain density material such as honey of washing, and in syrup, the solidliquid mixture of crystallization of sucrose and liquid mother liquor formation has just formed first cream under certain condition.
Second cream is after first cream is cooked into, and there are many white sugar particles the inside, very sticky, get rid of and be wrapped in white sugar fluent meterial on every side with the machine as Dewatering machine of washing machine (sugar centrifuge), has so just obtained solid state white granulated sugar.Throw away the fluent meterial that there is no crystallization come, the inside also has higher sugar to divide, and loses just unfortunately, and this thing is referred to as high green syrup.White sugar is depended drier alone and is also got rid of untotally, also will beat a little hot water or steam on surface, dry on one side, just can whiten.These hot water or steam are taken away again the sweet or sugared of some white sugar surfaces, and this just makes first wash honey.On deal, high green syrup accounts for mainly, and it is just a small amount of that first is washed honey.Then the thing that is the master in order to high green syrup boils one again and takes turns, and this is used for boiling sugared material and just is second cream.
The third cream be second cream cooked after, with drier, throw away honey again, the sugar stayed is called biose, throws away the honey come and just is the second green molasses, the second green molasses of take is main material, the sugar of the inside also has many, just boils again, this to take the second green molasses be main thing, just is the third cream.
The so-called cream of planting, be exactly in the boiling process of various massecuites, neat for ease of sucrose rapid crystallization and crystal in massecuite, generally exactly product white sugar is worn into to very tiny crystal grain as Icing Sugar, in the input crystallizer, add again corresponding honey material, when in the honey material added, sucrose reaches its degree of supersaturation, sucrose just is easy to be deposited on Icing Sugar, by for some time boiling, sucrose on Icing Sugar is gradually grown up and is become the sucrose crystal that naked eyes can be seen clearly, by such growing the grain process, Sucrose in the continuous absorption mother liquor of sucrose crystal in mother liquor, kind as various massecuite boilings.
